CHARLES H. GUNN, or OAKLAND, CALIFORNIA.

TOILET FLUSH.

Application filed September To all whom it may concern:

Be it known that I, CHARLES H. GUNN, a citizen of the United States, residing at Oakland, county of Alameda, State of California, have invented certain new and useful Improvements in Toilet Flushes; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to the plumbing art,- and particularly todevices for flushing toilets. The object of the invention is to provide an efficient flush which will give a quick and adequate supply of water under pressure; one which will be leak-proof; cannot become'air bound; be economicaland accurate in the amount ofwater used; and finally one which can be economically constructed and easily and quickly installed for use and easily kept in repair.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed.

These objects I accomplish by-means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the 7 several views Fig.1 is a side elevation of atoilet showing my improved flush installed ready for use.

Fig. 2 is a vertical cross sectional view taken on a line 2-2 of Fig. 1.

Fig. 3 is a cross sectional view taken on a line 33 of Fig. 1.

Fig. 41 is a sectional View taken relatively on a line M of Fig. 2.

Fig. 5 is a sectional iew taken relatively on a line 55 of Fig. 3.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 designates the flush tank of desired shape and size into which enters the water supply inlet pipe 2.

The discharge outlet 3 is relatively larger than the inlet 2, and said outlet 3 opening into'the still larger flush pipe 1. The pipe a is threaded into the bottom of the tank 1 and has a cross head 3 in which is formed the outlet 3, surrounding which is an up- 5, 1922. Serial No. 586,308.

turned flange 8 forming the seat for the closure valve 5, having a gasket 5, the valve and gasket being held in position on the bottom of a float 6 by means of bolt 6 Extending through the gasket, valve and oat.

Two upstanding pipes 7. are mounted on the 'cross head 3 and extend through the tank 1 andact as guides for the float 6 which is grooved or orificed as at 6 for the purpose. These pipes 7 also act as guides for rods 8 which extend into the outlet pipe 4. On the'lower end of said rods is a cross head 9 with springs 10 interposed between the cross heads 9 and 3 and around the rods 8.

The cross head 9 carries a valve releasing pin 11 for a purpose as will presently appear.

The head 12 of the tank 1 has a counter sunk interiorly threaded collar 13 terminating in an amiular seat 1 1. A plate 15 rests on said seat with an intermediate gasket 15 to make a water'and air tight joint.

The pipes project through holes 16 in the plate 15 surrounded by conical rubber gaskets 16 held in position by a plate 17 to make water and air tight joints. The plates 15 and 17 are clamped into position against their gaskets by a hollow nut 17 threaded into the collar 13.

18 designates a support extending upwardly from the plate 17 in which is pivoted the operating handle 19. Links 20 connect the handle 19 with clamps 21 into which are clamped the rods 8. A stop screw 22 mounted on the 'topof the plate 17 limits the movement of the clamps and consequently the rods 8.

The float 6 is nicely and arbitrarily balanced so that, aftera complete flushing the weight of the water, combined with the suction through the outlet 3 will pull the valve 5 closed and hold it firmly in that position while the tank fills again.

To flush the tank, the operator presses the handle 19. This pulls on the rods 8 and the cross head 9 carries the releasing pin 11 into control with the float valve and lifts it from the valve seat 3 The rush of the water through the opening 3 upsets the nice balance of and suction against the float 6 and it ridesor floats quickly to the top of the water, guided by the pipes 7 The float has a pointed end 6 which aids it in cutting quickly through the water.

a The springs 10 return the rods 8 and cooperating parts back to normal position and as the water flushes out the valve again,

closes over the outlet 3 whereupon the operation can be repeated.

Quick discharge of the water is had by reason of the pressure in the tank, which is air tight as described, and also as the discharge is taking place air is readily drawn into the discharge pipe 4 through the pipes 7-, thus obviating any tendency to vacuum.

The flushing apparatus as above described I cannot become air bound since the intake is at ll toadmit of adjustment of its length.

entirelyseparate from the outlet.

The parts of the device are so balanced and proportioned that the float travels clear to the top of the tank and back again with each flush so the exact amount of water is used each time.

The pin 11 has arubber tip 11 to engage the end of the bolt 6 and is thread jointed The upper end ofthe member 11 is nearly as large as the outlet 3, so that the water cannot begin to flush out until the float has been raised by the pin 11 and the-latter has dropped back to its normal position.

This gives the floata chance to get far enough away from its seat to eliminate the chance of the drag of the water reseating thefioat before the tank has been emptied- From the foregoing description it will be readily seen that I have produced such a de vice as substantially fulfills the objects of the invention as set forth herein.

\Vhfle tlns specification sets forth in. de-

tail the present and'prefei'red construction of the device, still in pra'ctice. such deviations from such detail may be resorted to as do not form a departure from the spirit of'the invention, as defined by the appended 7 claims.

Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent is: a a 7 1. A toilet flushing apparatus comprislower end; of the float adaptedto close the outlet, and pipes projecting upwardlyin the tank at thesides of the outlet,:the-sides ing a tank having an inlet andan outlet, a 7 float-controlled valve for the outlet a pipe below the outlet, pipes communicatingwith of the float being vertically grooved "to fit the pipes, whereby the latter form guides for the float. j 7 1 In testimony whereof I affix my signature.
